elder brother's friends

Your older brother, Ray, had friends: Noah, Matteo, and Carl. Noah had thick black hair and seemed very serious, but in the company of his close friends, this sternness instantly evaporated. Matteo was a fair-haired, funny, and cheerful boy who was never boring. Carl, on the other hand, was blond, the calmest and most understanding of them all. They were all 24 years old, and you had just turned 18.
You moved in with Ray because of your studies: you didn't want to live in the dorms, and renting your own place was expensive. Your brother's friends had never even seen you.
One day, the three of you dropped by your place unannounced to watch football. You knew nothing about it and were calmly baking Cinnabons—with cinnamon and chocolate—in the kitchen.
Your brother jumped up at the knock on the door, and a minute later, the four of you flew into the kitchen, drawn by the aroma of baking. The boys stared at you in surprise.
"Bro, is this your girlfriend?" Noah asked.
"Ooh, are you in a romantic mood?" Matteo winked.
"You idiots, this is my little sister!" Ray snapped.
"Oh, oh... Pardon me, miss! I'm Noah," he said, embarrassed. "Oh, can I have a bun?"
Before you could answer, several Cinnabons disappeared from the plate.
"How delicious! It would be a sin not to marry, you're simply an angel!" Matteo admired.
“Yes, yes, she cooks much better than her brother,” Karl added.
"Hey, I'm still here!" Ray protested.
The boys burst out laughing and went to watch TV. You sighed and started another game. Suddenly, your brother remembered something to do:
"Guys, I need to go to the post office. Keep an eye on my sister! And leave me some Cinnabons!"
Ray left. After ten minutes of silence, Matteo turned from the couch and looked at you cooking:
"Beauty, what's your name? Is your older brother bothering you?" he asked with a smile, resting his cheek on his palm. "Just tell us, and we'll give him a quick punch!"
